Advertising Taxes in Turkey: What Foreign Brands Need to Know
Three separate taxes touch digital advertising in Turkey, they have different payers, and only one of them is a genuine cost to the advertiser. Foreign teams routinely compress them into a single line called “the ad tax” and then build the Turkey budget wrong.
In short: the Digital Services Tax is levied on the platform, not on you — and its rate dropped from 7.5 percent to 5 percent on 1 January 2026, falling again to 2.5 percent in 2027. The advertising withholding tax is deducted by the Turkish payer at source and, depending on who you pay, is either 15 percent or zero. VAT applies at the general rate but is normally recovered through deduction, making it a timing and cash-flow item rather than a cost — provided it is declared and paid, which since 2024 is a condition of deducting it.
The counterintuitive part, and the one that matters most for structure decisions: if you have no Turkish entity and pay a foreign platform from abroad, you sit outside the Turkish withholding and VAT systems entirely. Establishing a Turkish company creates obligations that did not previously exist.
This guide sets out each mechanism, the legal instrument behind it, how the rate changes depending on who you pay, and how to model the real cost. It is general information, not tax advice — the analysis depends on your structure, and every figure here should be confirmed with a Turkish tax advisor before you budget from it.

The three taxes at a glance
| Tax | Legal basis | Who is liable | Real cost to the advertiser? |
|---|---|---|---|
| Digital Services Tax (DHV) | Law No. 7194; rate set by Presidential Decision No. 10767 | The platform providing the digital service | Indirectly, where platforms pass it through |
| Advertising withholding (stopaj) | Presidential Decision No. 476 | The Turkish payer, who deducts at source | Yes, where the contract requires grossing up |
| VAT (KDV) | VAT Law No. 3065 | The Turkish recipient, via reverse charge | Normally no — deductible once declared and paid |
Digital Services Tax
Turkey’s Digital Services Tax was introduced by Law No. 7194, published in the Official Gazette on 7 December 2019 and effective from 1 March 2020. It is levied on revenue rather than profit.
What it covers. Advertising services provided in a digital environment fall squarely within scope, alongside digital content sales and the provision and operation of platforms where users interact. Intermediary services relating to those activities are also covered. Notably, advertising services directed at persons who are not in Turkey are outside the scope.
The rate changed in 2026. Law No. 7194 set the rate at 7.5 percent, and gave the President authority to reduce it to as low as 1 percent or double it by service type. That authority was exercised: Presidential Decision No. 10767, published in the Official Gazette dated 25 December 2025 (No. 33118), set the rate at 5 percent from 1 January 2026 and 2.5 percent from 1 January 2027. The decision applies to revenue earned from those dates rather than retroactively.
If your agency or internal documentation still cites 7.5 percent, it is out of date. This matters for year-on-year comparisons — a Turkey media cost that appears to fall slightly in 2026 may partly reflect a tax change rather than an auction change.
The threshold is widely misread. Exemption applies to providers whose Turkey-derived revenue was below TRY 20 million or whose worldwide revenue was below EUR 750 million in the preceding accounting period. Liability begins only when both thresholds are exceeded. This is why the tax reaches the large global platforms rather than smaller ad networks.
You do not file this tax. The taxpayer is the service provider. Liable providers register with the Revenue Administration and file monthly. Your exposure is commercial rather than administrative: a revenue tax on a platform’s Turkish advertising business is a cost platforms have generally passed through to advertisers, sometimes as a visible invoice line. When benchmarking Turkish CPMs against another market, check whether the comparison is like-for-like on that pass-through.
One further note for completeness: the enforcement provision in Article 7 of the law that allowed access blocking for non-compliance was partly annulled by the Constitutional Court in a decision published in 2023, on the grounds that lighter measures should be applied first. Enforcement mechanics have therefore shifted, though the tax itself stands.
Advertising withholding tax
This is the mechanism with the most direct effect on a Turkish entity’s advertising costs, and the one foreign finance teams have usually never encountered.
Presidential Decision No. 476, dated 18 December 2018 and published in the Official Gazette on 19 December 2018 (No. 30630), brought online advertising services into the scope of income and corporate tax withholding. It applies to payments made from 1 January 2019 onwards, regardless of when the service was provided. Implementation guidance followed in Corporate Tax Communiqué Series No. 17, published in February 2019.
The structure is important. The obligation sits on the payer — those listed in Article 94 of the Income Tax Law and Article 15 of the Corporate Tax Law, which covers commercial companies, cooperatives, associations and foundations, public bodies, investment fund managers and self-employed professionals. Withholding applies to payments made both to those providing online advertising services and to those acting as intermediaries, and applies regardless of whether the recipient is a registered taxpayer in Turkey.
The rate depends on the recipient:
| Recipient of the payment | Legal reference | Withholding rate |
|---|---|---|
| Non-resident company (dar mükellef kurum) | Corporate Tax Law, Art. 30 | 15% |
| Real person, resident or non-resident | Income Tax Law, Art. 94 | 15% |
| Resident company (tam mükellef kurum) | Corporate Tax Law, Art. 15 | 0% |
That final row is the one to internalise, because it turns the whole question into a practical decision about invoicing routes.
The rate depends on who you pay
Two Turkish companies can run identical campaigns on the same platform and face different withholding outcomes, purely because of which entity issues their invoice.
If your Turkish company pays a Turkish-resident entity of the platform — a local subsidiary that invoices in Turkey — the withholding rate under Article 15 is zero. If your Turkish company pays a non-resident entity of the same platform directly, withholding at 15 percent applies under Article 30.
It is tempting to assume that a Turkey billing country means a Turkish invoice. It does not reliably. Google’s own documentation indicates that accounts may be served by Google Ireland Ltd., while certain accounts for affected products may move to being served by Google’s Turkish entity following notification — so the contracting entity depends on the account and the product, not simply on the billing country. Meta and other platforms likewise maintain local presences in various markets, and the existence of a local company should not be equated with local invoicing of your particular account.
The practical rule for withholding and VAT analysis is therefore: do not reason from billing country, reason from the document. Look at which legal entity is actually named on your invoice and in your advertising terms, confirm it has not changed since you last checked, and have your accountant determine what that specific entity implies. Platforms restructure their contracting arrangements periodically and notify advertisers when they do, so this is worth re-checking rather than establishing once. It is the single highest-value thing a foreign brand’s finance team can verify in its first month of Turkish operations.
The same question applies to intermediaries. If you buy through an agency or a programmatic partner, the withholding analysis follows the chain of payments, and the Decision explicitly covers payments to those who act as intermediaries in providing online advertising. Establish where in the chain withholding arises before signing a media buying agreement — a point worth raising when choosing a digital marketing agency in Turkey, and relevant to the contracting structures described in our guide to programmatic advertising in Turkey.
Grossing up: the cost nobody budgets for
Withholding is deducted from the payment to the supplier. In theory the supplier bears it. In practice, large platforms and many suppliers contract on a net basis — they expect to receive the full agreed amount — which means the Turkish payer must gross up.
The arithmetic is straightforward but the effect surprises people. If a supplier must receive TRY 10,000 net and the withholding rate is 15 percent, the gross amount is TRY 10,000 divided by 0.85, or approximately TRY 11,764.70. The withholding is roughly TRY 1,764.70, and the true cost of the media is not 15 percent higher than the net figure but closer to 17.6 percent higher.
This is a real, unrecoverable cost, unlike VAT. A Turkey media plan built from net platform costs without grossing up understates spend by a material margin — which is why this belongs in the budget model alongside the channel costs covered in our budget guide to digital marketing costs in Turkey.
VAT and the reverse charge
Advertising services used in Turkey are subject to Turkish VAT. Where the supplier has no residence, workplace, legal centre or business centre in Turkey, the recipient accounts for the VAT itself under the reverse charge mechanism: it is declared on the No. 2 VAT return (KDV-2), paid, and then deducted on the No. 1 VAT return under the general rules.
Since 2024, deduction depends on payment. This is the change most foreign finance teams have missed. Law No. 7491, published in the Official Gazette on 28 December 2023, added subparagraph (ç) to Article 29/1 of the VAT Law with effect from 1 January 2024, making the deduction of VAT declared under the reverse charge conditional on that VAT having been paid. Procedures were set out in VAT General Application Communiqué amendment Series No. 50, published in February 2024.
The timing consequence is specific. Where the KDV-2 return is filed within the statutory period and the tax is paid within that same period, the VAT can be deducted on the No. 1 return for the period in which the transaction occurred — the position that applied before. Where it is paid late, the deduction moves to the period in which payment was actually made. A missed payment deadline therefore does not forfeit the deduction, but it does push it into a later period.
Two further practical points.
It is normally a timing and cash-flow item rather than a cost. For a VAT-registered business with sufficient output VAT, the amount paid under the reverse charge is recovered through deduction. Businesses carrying a persistent VAT credit position do not lose the deduction, but they may not be able to use it against output VAT for some time, which can create a cash-flow and working capital burden. How material that is depends on the size of the credit position and how quickly it unwinds.
The obligation applies even to non-VAT-registered recipients. Turkish guidance is explicit that those without VAT registration must still declare and pay under the reverse charge for such services.
Skipping the declaration is a documented audit risk. Some businesses treat the exercise as pointless on the assumption that it nets out. Turkish tax practitioners warn that inspectors assess the unpaid KDV-2 without allowing the corresponding deduction, producing an assessment plus penalty for what the taxpayer believed was a neutral transaction. Under the payment condition described above, that exposure is greater than it was before 2024, since deduction now depends on payment having been made. Cross-checking against bank records for foreign payments is standard practice.
Confirm the current general VAT rate with your advisor when modelling, as rates are subject to change.
A worked example
The figures below are illustrative and use a single round number to show the mechanics — they are not market rates. Assume a Turkish company buying TRY 100,000 of advertising, net to the supplier, and a 15 percent withholding rate.
| Line | Paying a non-resident platform entity | Paying the platform’s Turkish entity |
|---|---|---|
| Net amount to supplier | 100,000 | 100,000 |
| Grossed-up base | ≈117,647 | 100,000 |
| Withholding (stopaj) | ≈17,647 — real cost | 0 |
| VAT treatment | Reverse charge via KDV-2; deductible once paid | Charged on the invoice, then deducted |
| Approximate net cost of media | ≈117,647 | 100,000 |
The gap between the two columns is not a rounding difference. It is the reason invoicing route deserves finance team attention before media planning begins.
Treaty relief and why it is contested
Turkey has an extensive double taxation treaty network, and the standard business-profits article in those treaties generally allocates taxing rights over a foreign company’s business profits to its country of residence where it has no permanent establishment in Turkey. On that reading, withholding on advertising payments to a treaty-resident platform with no Turkish permanent establishment should not apply, provided a certificate of residence is furnished.
This argument has been litigated in Turkey, and the outcomes have not been uniform. Lower courts have in some cases accepted the treaty argument, while the Council of State has in at least one reported decision upheld withholding under Decision No. 476 notwithstanding the treaty position. The Revenue Administration has issued rulings supporting the application of withholding.
The practical implication for a foreign brand is not that treaty relief is unavailable, but that it is an area of genuine legal dispute where the answer depends on the specific treaty, the facts, and current case law. Do not plan a Turkish media budget on the assumption that treaty relief will apply automatically. Get a written position from a Turkish tax advisor, and obtain residence certificates where relevant.
What changes when you set up in Turkey
This is the structural point that reframes the whole topic.
A foreign company with no Turkish entity, paying a foreign platform from abroad for campaigns targeting Turkey, is not a payer under Decision No. 476 and is not a Turkish VAT recipient. It sits outside both mechanisms. Its only exposure is the Digital Services Tax, indirectly, to the extent the platform prices it in.
Establish a Turkish company, and that company becomes a payer within the meaning of the relevant articles. Withholding obligations and VAT reverse-charge declarations begin with the entity, not with the advertising.
None of this is an argument against incorporating. Local structure unlocks local payment acceptance, local contracting and local hiring, which in consumer categories usually outweighs the fiscal difference by a wide margin. It is an argument for modelling the fully loaded cost of local media buying before the entity exists, so the finance team is not surprised in month two. The broader structure question is covered in our guide to marketing in Turkey for foreign brands, and the operating model choice in agency vs. in-house team in Turkey.
Common mistakes
Still using the 7.5 percent DST figure. The rate has been 5 percent since 1 January 2026 and falls to 2.5 percent in 2027.
Reading the DST thresholds as alternatives. Both the TRY 20 million Turkey threshold and the EUR 750 million global threshold must be exceeded for liability to arise.
Budgeting net platform costs without grossing up. Where 15 percent withholding applies on a net-basis contract, the true cost is roughly 17.6 percent above the net figure.
Assuming withholding is a flat 15 percent. It is zero on payments to a resident company — which is why the invoicing entity matters so much.
Skipping or late-paying the KDV-2 declaration because it nets out. Since 2024 the deduction depends on the tax having been paid, and non-declaration is a documented source of assessments and penalties.
Treating treaty relief as automatic. It is contested in Turkish case law and requires a considered position, not an assumption.
Confusing these taxes with data protection obligations. They are entirely separate regimes; KVKK compliance runs in parallel and is covered in our guide to KVKK compliance for foreign brands.
Frequently asked questions
What is the digital services tax rate in Turkey?
Law No. 7194 set the rate at 7.5 percent, but Presidential Decision No. 10767, published in the Official Gazette on 25 December 2025, reduced it to 5 percent for revenue earned from 1 January 2026 and 2.5 percent from 1 January 2027. The tax is levied on the digital service provider, not on the advertiser.
Do I pay digital services tax as an advertiser?
No — the taxpayer is the platform providing the service, and only where both the TRY 20 million Turkey revenue and EUR 750 million global revenue thresholds are exceeded. Advertisers may nonetheless bear part of the cost where platforms pass it through in pricing.
What is the withholding tax on online advertising in Turkey?
Under Presidential Decision No. 476, payments for online advertising services are subject to withholding by the Turkish payer: 15 percent on payments to non-resident companies and to real persons, and 0 percent on payments to resident companies. The obligation applies regardless of whether the recipient is a registered taxpayer in Turkey.
Does a foreign company without a Turkish entity pay these taxes?
Generally not directly. A foreign company paying a foreign platform from abroad is not a payer for withholding purposes and is not within the Turkish VAT reverse-charge system. Establishing a Turkish entity creates both obligations. Confirm your own position with a Turkish tax advisor, as it depends on your specific structure.
Is VAT on foreign advertising services a real cost?
Usually not, provided it is handled correctly. It is declared on the No. 2 VAT return and, since 1 January 2024, can be deducted on the No. 1 return only once it has been paid — on time, and the deduction falls in the period of the transaction; late, and it falls in the period of payment. For a business with sufficient output VAT it is therefore a timing and cash-flow item. Businesses carrying a persistent VAT credit position keep the deduction but may not be able to use it promptly, which can create a working capital burden. The declaration itself is not optional.
Can a double taxation treaty eliminate the advertising withholding?
It is arguable and has been litigated, with mixed outcomes — lower courts have accepted the treaty argument in some cases while the Council of State has upheld withholding in at least one reported decision. Treat it as a contested position requiring professional advice and a residence certificate, not as an automatic exemption.
Conclusion
Advertising tax in Turkey is not unusually heavy, but it is unusually easy to model wrongly, because the three mechanisms have different payers and only one of them is a real cost. The Digital Services Tax reaches you only through platform pricing, and at a lower rate in 2026 than in prior years. VAT nets out for most businesses, provided you declare it and pay it on time — since 2024 the deduction depends on payment. Withholding is the item that moves the budget — and its rate turns on which legal entity issues your invoice, a detail most foreign finance teams have never checked.
Work through it in that order: confirm the invoicing entity, establish whether your contracts are net or gross, model the grossed-up cost, and get a written position on treaty relief rather than assuming one. Do that before the media plan is signed off, and Turkey becomes a market you can budget accurately. Do it afterwards, and the variance shows up in month two with no good explanation.
